17 Claims.

This invention relates to apparatus and method of salvaging the remnants of newsprint paper which are left on the cores of the rolls of paper r after the bulk of such rolls has been used in the printing process.

In present practice, a roll of paper for newspaper printing will run approximately thirty inches in diameter, including a three and one half inch diameter core. All of the paper on the roll can be used in the ordinary printing process, except approximately a half or three-quarter of an inch in thickness of paper surrounding the core, which remnants are removed from the press with the core and are frequently discarded and wasted, no method or apparatus having been devised for the purpose of utilizing or saving these remnants. This loss in a newspaper plant is very considerable, especially where the cores are of 20 paper or other material which does not fully protect the inner layers of print paper which frequently become damaged at the edges.

The present invention consists of amethod of saving such remnants and an apparatus for operating said method.

The method and apparatus respectively involve many steps and structures which are common in the handling of paper under other conditions.

The invention consists, primarily, in the combination of steps already in use in the art of handling paper, such combination resulting in a new method and giving a new and beneficial result and the invention also includes certain new steps and/or improvements upon the old steps, in order to adapt the combination of the old steps to the efficient accomplishment of the new purpose. As to the apparatus, the invention likewise consists, primarily, in the combination of structures and parts now known and used in the art of handling paper, the structures and parts being so combined as to accomplish a new and beneficial result and the invention likewise consists in the provision of certain new parts and structures and/or the improvement of old parts and 0 structures, in order to adapt the combination to the emcient accomplishment of the new purpose.

An object of the present invention is to provide a method of salvaging remnants of newsprint paper, comprising the unwinding of the remnants, the splicing thereof into a continuous strip, the re-winding thereof into a roll adaptable for use upon a press taking its supply of paper from a roll, including in such process, the slitting of the paper to eliminate damaged edges and the reduction of the paper todesired. width.

A further object, is to provide an apparatus for the unwinding of remnants of newsprint paper from cores, for the splicing of the same into a continuous strip, for the trimming of damaged edges from such paper, and'the re-winding of the trimmed and spliced paper into a roll for use upon a press. 7

A further object, is the provision, in an apparatus of the above described type, of new and. improved arrangements of tension and guiding means.

A further object, is the provision in such an apparatus of a new and improved combination of slitting, splicing and tensioning means.

Afurther object, is the provision of new and improved means in such a device for the disposition of the trimmed waste.

Other objects will appear from, and be defined in, the following "specification and appended claims and illustrated in the accompanying drawings, in which likecharacters of reference indicate corresponding parts throughout and in which Figure I is a plan of the apparatus, showing a web of paper in passage thereover from a rough rollof spliced remnants to two short finished rolls, portions of the web and of the apparatus being broken away to disclose certain parts, and certain other and hidden portions being shown in dotted lines.

Figure II is a side elevation of the apparatus operating as in Fig. I and showing certain hidden portions in dotted lines and indicating the line of passage of paper over the machine.

Figure III is a section of line A-A of Fig. I, showing a rough roll of spliced remnants being re-wound into two short finished rolls.

Figure IV is a section of line A-A of Fig. I but with the machine arranged for unwinding remnants from the cores, splicing the remnants and Winding them into the rough roll, certain parts, shown in the previous figures and involved only in the winding of the finished, roll, being omitted.

Figure V is a View of the driving mechanism and certain associated parts.

Figure VI is a view, in detail, of a modification of a portion of the machine by which the remnants are unwound, spliced, trimmed and wound into the finished roll, in a single operation, without the intermediate winding into a rough roll.

Figure VII is a plan of a portion of the machine showing arrangement for salvaging remnants of two short rolls simultaneously together with the arrangement of central slitters and convcyor for dividing a wide strip of paper into two narrower strips.

Figure VIII is a detail fragment in elevation showing, both in and out of use, the flanges which hold the cores agaist longitudinal movement during the unwinding thereof.

Figure IX is a plan, partly in section, showing the rewind tension rollers and associated parts.

Figure X is a detail view of the construction at the end of the tension rollers.

The apparatus is so constructed that the operation from and including the unwinding of the remnants from the cores to and including the winding of the finished rolls of spliced and trimmed paper may be carried on, either in a single, continuous process or by first winding the spliced paper into a so-called rough roll and thereafter unwinding from said rough roll, passing the paper through the desired trimming, slitting, tensioning and guiding means and winding it into the finished roll or rolls. The apparatus will first be described in relation to the double operation, involving the intermediate winding and unwinding of the rough roll. Thereafter the modification, whereby the winding and unwinda ing of the intermediate rough roll is eliminated,

will be described.

Parts referred to or described in general terms and without detailed description, are standard and well known and may be of any well understood construction suitable for the purpose indicated.

On suitable standards 1, and preferably integral therewith, there are provided sides 2, which sides are provided with bearings and supports for the rollers, guides and other parts of the machine and for the rolls and cores, all as hereinafter described, and it will be understood that the tension and guide rollers, pipe rollers and rolls of paper hereinafter described, are revolubly mount-- ed at their two ends in suitable bearings in the sides 2, the particular construction of the bearings forming no part of this invention, except in cases, and as to features, hereinafter more particularly described.

In the operation of the apparatus involving the intermediate rough roll, rollers 3 and 3' are provided, revolubly mounted in the sides 2 and spaced apart so as to rollingly support a core 4 with a remnant of paper 5 thereon, roller 3 being provided with flanges 3x slidably mounted thereon and provided with any suitable means, as set screw 3y for setting the flanges at any desired positions along roller 3' so as to prevent longitudinal movement of core 4.

Another roller 6 is revolubly mounted in a raised portion of the sides 2 and adjacent thereto is a splice board 7 suitably mounted at its two ends upon the said raised portion of the sides 2 and having its top or splicing surface adjacent to, but

preferably slightly below, the top of the roller 6.

Parallel to the splicing board 7 and to the roller 6, but on the opposite side of the splicing board '7 from the roller 6 and preferably with its top slightly above the 'top of the splicing board '7,

is revolubly mounted a compensating roller 8, compensation being provided for by springs 9 on both sides of the bearing 10 of the roller 8, which bearings are slidable in a boxed runway 11, whereby the bearing will normally remain in the longitudinal center of said runway by reason of the equal pressure of the springs 9 on the opposite sides thereof, but which bearings may move longitudinally in said runway in either direction, as pressure is exerted on the roller 8 against the 7 pressure of either of the springs.

Core 12 is mounted on chucks 13 carried by shaft 15, revolubly mounted in sides 2, means, as sprocket 16, being provided for receiving power from any suitable source, as through the chain 17, for revolving the shaft 15 with the chucks 13 and core 12 mounted thereon. A suitable brake is provided, consisting of a drum 18, with a band 19 therearound, having one of its ends suitably fastened as at 20 and the other end being provided with a suitable weight 21 for exerting braking friction upon the drum 18, which is mounted on the shaft 15. All as clearly shown at Fig. 1.

In operation of the structure thus far described, the core a, with the remnant of paper 5 thereon, is placed upon the rollers 3 and 3 and the end of the remnant 5 is led under and around the roller 3', thence upward and over the roller 6, across the splicing board 7 and over the compensating roller 8 and is suitably fastened to the core 12. Thereupon power is applied to sprocket 16, resulting in the revolution of the core 12 in the direction of the arrow at the left in Fig. IV, thus winding the paper on to the core 12, the core 1 being caused to revolve in the direction of the arrow adjacent that core, in Fig. IV. The drawing of the paper from the core 1 will cause that core and its remnant of paper to roll upon the rollers 3 and 3' in the direction of the arrow until all of the remnant of paper thereon is drawn from'the core except the last few laps or layers which are frequently not in usable condition. After the end of the usable portion of the remnant leaves the core l, the revolution of the core 12 is stopped. Thereupcn another core 4, with its remnant of paper 5, is placed upon the rollers 3 and 3, the outer end of the remnant is drawn under the roller 3 and over the roller 6, whereupon a strip of splicing material, preferably splicing Para rubber, is placed between the overlapped ends of the two remnants and a hot iron is run over the three layers, resulting in an efiicient, flexible and practically invisible splice in the paper. Thereupon, the end of the top sheet is trimmed off, adjacent the splice. The strip of paper is then moved forward by revolution of core 12 until the splice is on the outer side of the rough roll'on core 12, whereupon the ragged end of the lower sheet, which will then be the outer sheet, is trimmed off adjacent the splice, leaving a clean splice with two clean trimmed ends or edges. Thereupon the rough roll on core 12 is again revolved, resulting in the unwinding of the second remnant from the core 4 and winding thereof on to the rough roll, until the end of said remnant is reached, when a third core is placed upon the rollers 3 and 3' and the above described splicing and trimminig operation is repeated. These operations are repeated until sufficient remnants have been supplied and wound upon the rough roll to make a roll of the desired diameter.

In making finished rolls from the rough rolls, the direction of movement of the paper through the machine is reversed and some changes are made in the machine. The rough roll remains revolubly mounted, as in the operation above described, and the paper is drawn therefrom over the compensating roller 8 and the roller 6, the roller 6 being provided with a plurality of grooves 6a arranged therein and spaced therealong as desired. Parallel to the roller 6 and suitably spaced therefrom, is a slitter'shaft 22 revolubly may be provided for setting the slitters on the shaft 22. When they paper is passing .over the roller 6 the shaft 22 is mounted in position, as indicated in Figs. I, II and III, the slitt ers 23 being already set for co-action with the proper grooves 6a for trimming off the rough edges and trimming and/oi slitting the paper to the desired width. The slitting structure here described and the operation thereof, are standard.

From the roller 6, the paper is passed under and around a second compensating roller 25 of structure and mounting similar to compensating roller 8, as hereinabove described, and as clearly shown in Figs. II and III and shown but not in use in Fig. IV.

A roller 26, of any suitable material, as, for instance, steel core with composition coating, is positioned upon the rollers 3 and 3 and held against longitudinal movement by any suitable means, as

by ends 26 of the roller shaft, bearing against arms 26" secured to the sides 2, all as clearly shown in Figs. I, II, III, IX and X and the paper is led around the roller 3', over the roller 26 in the direction of the arrow in Fig. III, down and around the roller 3 and thence directly to the finished roll core 27, or through the slitting and ang1ebar devices hereinafter described, to the finished roll core, according to whether it is desired to make a single finished roll or a plurality of finished shorter rolls from the one strip'of paper. If the paper is to be re-wound into a single finished roll, no mechanism intervenes between the roller 3 and the finished roll core 27, but when it is desired to produce from the strip of paper, two shorter finished rolls, as indicated in Fig. I, a grooved roller of the construction of roller 6 is used as roller 3 and the slitter and angle-b'ar mechanism, now described, is interposed in the track of the paper between such roller 3 and the finished roll core 27 and Figs. I, II and III disclose the slitter' and angle-bar construction, which consists of a slitter shaft 28, revolubly mounted in the sides 2 and provided with a slitter 29 with set screw 30 for slidably adjusting the slitter on the shaft to cooperate with a groove 30. in such roller 3, the relative position of the slitter 29 and a groove 29' in such grooved roller 3, being clearly shown at Fig. I, the purpose being, to slit the strip of paper for dividing it into two narrower strips. This slitting construction and operation'is standard and needs no further description. It will be noted, however, that the mounting for the slitter shaft 28, comprises notches 31 in the sides 2, whereby the slitter shaft may be readily removed when the slitting of the paper is not desired, or positioned when slitting is desired.

Angle bars 32 are mounted-upon and between the sides 2, said bars being of smooth surface to permit the paper to slide therearound and being positioned and angled for engaging and separating the two strips of paper, so that they will be wound into two finished rolls which shall be separated, as clearly shown at the right in Fig. I, the separation being necessary in order to prevent relative overlapping or other interference of the adjacent edges of the two strips and to insure uniformity of the finished rolls throughout their lengths. Angle bar construction and operation for changing the relative positions of two strips of paper as desired is well understood by those skilled in the art and needs no further description.

In Fig. VII a further modification is illustrated whereby a wide strip of paper may bedivided into two narrower strips without the use of the slitter 29 and angle bars hereinabove described, this modification consisting of the provision of two slitters 23 positioned in proximity to each other and at the desired points along the shaft 22 and in proper position relative to some of the grooves 6a in the roller 6, whereby said two slitters will cut a narrow strip from the web of paper passing over roller 6, resulting in dividing the same into two narrower webs with their adjacent edges smooth trimmed by said slitters. The narrow strip cut from the web of paper will be carried away-by a conveyor 37 of the type hereinafter more fully described, which conveyor will be positioned below said pair of slitters, as clearly shown, centrally of Fig. VII.

A weighted band brake 33 is provided on the end of the shaft of roller 3 'for giving the desired tension to the paper as the one or more strips thereof pass around the roller 3.

Further tension is provided by reason of the fact that the finished roll core draws the paper over and around the roller 26 and under and around the rollers 3 and 3, thus drawing these rollers tightly together and thereby highly tensioning the paper as it is wound onto the finished roll. By reason of the relatively rolling mounting of the rollers 3, 3 and 26, a very high degree of tension may be obtained without danger of breakage to the paper.

It will be understood that the core 27 of the finished roll is mounted upon chucks, similar to the chucks 13, these chucks being carried on a shaft 34 revolubly mounted in the sides 2, having means, as sprocket 35, for receiving power from any suitable source as through chain 36, for revolving the finished roll core 27.

Endless conveyors 37 are mounted beneath the slitters 23, as at 38, and extend beyond the finished roll, being there supported by suitable brackets 39, having a suitable height adjusting mechanism 40, the conveyors being operated by any suitable means, as by gear 41 carried by the conveyor shaft mounted at 38 and engaging gear 42 adaptedto receive power from any suitable source as through the chain43. The strips of paper trimmed or slit from the main web will drop on to the conveyors and be carried away to a point beyond the finished roll, thus preventing entangling of these strips with the mechanism or the finished roll. The belt conveyors 37 are geared to move somewhat faster than the web of paper from which the trimming is slit so that the conveyor will always tend to drag the slit strip from the machine and thereby prevent any accumulation of such strip until it has been carried away from and beyond the machine by the conveyor.

The sides 2 are provided at 44 with mountings for pipe rollers 3a and 3b and when it is desired to splice, trim and wind the paper into a finished roll, directly from the core, without the inter mediate winding and unwinding of a rough roll, pipe rollers 3a and 3b as clearly shown at Fig. VI are positioned in the mountings 44 and the core 4 with remnant 5 of paper thereon is positioned upon these rollers. The remnant of paper is drawn from the core 4, under the roller 3b, up and over the compensating roller 8 and across the splicing. board 7 and downward over the roller 6.

The spicing operation on the board will be the same in this modified structure as that already described, except that the paper will be moving in .the opposite direction and trimming of the underneath ragged edge, adjacent the splice, may take place on the outside of the finished roll 2'7.

In this modification, the trimming of the edges, the conveying away of the trimmed portions, the passage of the paper around the compensating roller 25, through the combination of rollers 3, 3' and 26 and to the finished roll 2'7, either in a single strip orin two strips formed in any of the hereinabove described methods, will be the same as that hereinabove described when the paper is drawn from a rough roll. A repetition of the description of this operation is thought to be unnecessary.

Except where otherwise clearly shown, the shafts of rolling parts, rest upon half bearings, provided in the sides 2, the bearingsbeing completed by a box placed thereover and secured to the sides 2 by any suitable means, allowing quick removal of the same, as for instance a box 45, Fig. II secured to the framework 2 by wing-nuts 46 and as also clearly illustrated by box 47, Figs. I and II secured to the sides 2 by a lug 48, fitting under a band 49 mounted on the sides 2, the other end of the box being secured to the sides 2 by wing-nuts 50.

It will be obvious that this apparatus and method may be employed for eliminating from rolls of'paper, portions which may have been damaged in transit or otherwise. For such use the roll of damaged paper is placed in the apparatus in the position hereinbefore assigned to the rough roll for re-winding the same into a finished roll. The operation will then be, in substance, the same as the operation hereinabove described for unwinding the paper from the rough roll and trimming and re-winding the same into finished rolls, including the slitting thereof into narrower widths when desired. In such a case splicing is not involved as the damage is to the ends of the rolls, which means, to-the edges of the strip of paper, so'that the trimming of the damaged edges is all that would be required in order to eliminate damaged portions.

- It will be understood that in practice, the paper used in newspaper work varies in width from as high as 72 inches down to 17 inches, various widths between these two limits, being employed. The apparatus and method hereinabove described may obviously be employed to produce finished rolls of any of these widths, except the original full width, this maximum width being impossible because of the trimming of the damaged edges.

The gearing and driving mechanism is here shown conventionally, it being understood that shaft 51 is connected with any suitable source of power and is supported in any suitable manner not here shown. This shaft carries a gear 52 for alternately meshing with gear 53 for revolving shaft 54, carrying sprocket 55 for driving shaft 15 through chain 1'7, andwith gear 56 for revolving shaft 5'7 and sprocket 58 carried thereby for driving shaft 34'through chain 36, also gear 59 and sprocket 60 for driving through suitable gears and chains the cutter and conveyor shafts, hereinabove described] Lever 61 is pivotally mounted above the shaft 51 and suitably connected to the gears 53 and 55 for alternately meshing said gears with the gear 52.

Any suitable device, such as a standard roll shifter in use on printing presses and conventionally indicated at 62, may be provided for longitudinally shifting the rough roll soas to make a deeper trim on one end or the other, according to the depth of damage on the respective edges, without shifting the slitters 23.

V In Fig. VII, in addition to the illustration of the slitters for dividing a wide web of paper into two narrow webs, as hereinabove described, there is disclosed an arrangement of parts whereby the remnants from two short cores may be simultaneously unwound and there are also clearly illustrated in Figs. VII and VIII the flanges on the roller 3 which holds the cores against longitudinal movement when the cores are resting upon the rollers 3 and 3. The operation of unwinding the remnants from two short rolls will be the same as that of unwinding from one long roll, with the exception that the two short rolls will be held in relatively spaced relation by a flange 3:: so positioned on the rollers 3 as to separate the adjacent ends of the cores, all as clearly illustrated at Fig. VII. The outer ends of the rolls are held against longitudinal movement by other flanges 3:13. The use of these flanges would be the same for the outer ends of a single long core to prevent longitudinal movement thereof, but in the case of the use of the single long core the central flange would, of course, be eliminated. The flange above described for use in separating two short cores, may be split so as to be readily removable from the roller 3'. The method of making such a split flange for quick removal will be readily understood by those skilled in the art and need not be further described. Any flanges not in use on the roller 3' may be slid from the end thereof so as to idle upon the shaft of the roller 3, as clearly shown at Fig. VIII.

It will be understood that many changes in detail of construction may be made, without in any manner departing from the spirit of the invention, as defined in the appended claims and without changing the operation of the method for salvaging remnants of newsprint paper.
